Managed Postgres
Technical reference for database clusters
Managed Postgres provides fully managed database clusters inside your projects. For a conceptual overview see Database Clusters, and for setup steps see Create and Connect to a Database Cluster.
Managed Postgres is available for organizations on the Pro plan.
Engine
| Property | Value |
|---|---|
| Database engine | PostgreSQL 18 |
| Connection pooling | Available by default (pooled URI) |
| Concurrent connections | Up to 10,000 per cluster (with pooled URI) |
Scaling
Clusters scale compute automatically with load.
| Property | Value |
|---|---|
| Compute range | 0.25–8 vCPU |
| Memory range | 1 GB–32 GB RAM |
| Scale-to-zero | After 5 minutes with no traffic |
A cluster scaled to zero wakes automatically on the next connection, so the first query after an idle period transparently scales it back up. Clusters are deployed geographically close to their project's compute.
Limits
| Limit | Value |
|---|---|
| Clusters per project | 20 |
| Cluster name characters | Letters, numbers, spaces, and hyphens |
| Cluster name uniqueness | Must be unique within the project |
Billing
Managed Postgres is billed by usage across three dimensions.
| Dimension | Unit | Description |
|---|---|---|
| Compute | RAM GB-hours | Memory allocated to the cluster, measured over time |
| Storage | GB-hours | Data stored in the cluster, measured over time |
| Data transfer | GB | Outbound data transferred from the cluster |
Because clusters scale to zero when idle, a cluster that is not serving traffic accrues no compute charge for that period. Storage continues to be metered while data is retained.
If your organization's managed Postgres usage exceeds the plan's limits, clusters are suspended until the next billing cycle. See Plans & Billing for how managed Postgres fits into your subscription.
Deletion
Clusters are permanently deleted in any of the following cases:
- You delete a cluster manually.
- Your organization downgrades to a plan that does not support managed Postgres.
- Your organization's subscription is canceled.
Deletion is irreversible. Back up any data you need before downgrading or canceling.
